Automatic Installation

Windows

Start COMSOL Multiphysics. In the Help menu,
select Check for Updates. If a COMSOL Update is available, click Download

Linux and Mac

Start COMSOL Multiphysics. In the Help menu, select Check for Updates. If a COMSOL Update is available,
you need to first exit COMSOL Multiphysics. Start a shell and cd to the root of the COMSOL 4.3b installation.
As root or with sudo priviliges, type setup/setup update.

Manual Installation

Check your version

Make sure that you run COMSOL version 4.3.2.152 or later. On the Help menu,
click About COMSOL Multiphysics to check your version. If you have an
earlier build number, contact your COMSOL sales representative to get
the official release of COMSOL 4.3b before you proceed.

Install

Before you proceed with the installation, make sure to exit any running COMSOL process.

Windows

Run the downloaded .exe-file to extract the update to the COMSOL 4.3b installation directory, for
example C:\Program Files\COMSOL\COMSOL43b. You can install the updates for the different products in any order.

Linux

Copy the downloaded .zip-file to the COMSOL 4.3b installation directory:

cp comsol_4.3.2.189_linux.zip [installdir]/comsol43b

where [installdir] is
the root of the installation, for example /usr/local. Unzip it by the
commands:

cd [installdir]/comsol43bunzip -o comsol_4.3.2.189_linux.zip

If you have not disabled SELinux, run the following command:

chcon -t textrel_shlib_t [installdir]/comsol43b/lib/[platform]/lib*

where platform is glnx86 or glnxa64.

Macintosh

Double-click the downloaded .dmg file to mount the disk image. In the Finder, open the mounted disk and double-click the COMSOL installer icon. Select your COMSOL installation folder, usually called COMSOL43b.

Check your installation

Start COMSOL Multiphysics.

On the Help menu, click About COMSOL Multiphysics.

Check that the version number is 4.3.2.189 (If not, the installation did not succeed).

Update Details for Update 1

COMSOL Multiphysics

Geometry objects that you add to a Work Plane's Plane Geometry no longer hide any projected or intersected wireframe.

The mesh generation no longer creates an unnecessarily fine mesh for some 3D geometries.

Creating a swept mesh for a domain with isolated linking faces now works.

The Circular edge plane type for work planes now works correctly also when you run in a client-server mode.

PMLs now work together with geometries that include virtual geometry operations.

Fixed a problem with units in inputs for a few user-defined functions.

Results while solving now works correctly for models with multiple studies.

Performance improvements for the SOR line, Vanka, and SCGS solvers.

Improved handling of probes.

Multiple plots in the same plot group now appear correctly using DirectX rendering.

Fixed graphics problem for Mac OS X 10.7 and 10.8.

Fixed problem that occurred when exiting the program on Linux.

Minor improvements for the sensitivity and optimization functionality.

Improved stability and user interface.

AC/DC Module

In the Magnetic Field Formulation physics, selecting Linearized resistivity and then changing the Conduction current relation in Faraday's Law now works correctly.

Structural Mechanics Module

Avoids error conditions that could appear when mixing a Linear Elastic material with a Linear Viscoelastic material in 2D Plane Stress and when adding a Linear Elastic material after a Linear Viscoelastic material.

Corrected an error when Prescribed Velocity or Prescribed Acceleration was used in a fluid-structure interaction analysis.
